Issue Description:
IRGen appears to have grown compile-time conditionalizations on host properties, e.g.:
https://github.com/apple/swift/blob/master/lib/IRGen/GenEnum.cpp#L3892
This is not correct if cross-compiling for a target with different endianness than the compiler host. This should check the properties of the target instead of being a #if
